It will likely be a much cheaper option to get a 2nd user part from a breakers yard and fit that - but I would only recommend doing that if you are suitably equipped and experienced to be confident about working around electrical systems and have read the procedure first...

If nothing else remove the batter -ve lead before you start and reconnect it only when you have finished.

If you do get a new one, best to get the whole job done at a dealer, they will confirm the diagnosis and you therefore have some comeback if they dont fix it.
